Abstract

Many people have observed a strange Gravity Hill Mystery on strange slopes of paved roads at hundreds of locations all over the world. Vehicles with transmission shifted to neutral gear and brake released simply roll uphill on such Gravity Hills. Furthermore, in several known Mystery Spot areas, a well known Shrink-and-Grow Mystery is the significant change of relative heights of two persons when they switch their standing positions on a level demonstration platform.

Many people simply dismiss these two strange mysteries as illusion.

On the other hand, in my 23-year research, I have found eleven sets of evidences to show that (1) the Illusion Theory is wrong for these two famous mysteries, and (2) the Gravity Hill Mystery and the Shrink-and-Grow Mystery are real and are caused by existence of significant abnormal local gravity, especially with significant horizontal component of gravity, at those special locations of Gravity Hills and Mystery Spots.

This important finding opens up the path for my research leading into the next important finding that the gravity mysteries at these special locations of Gravity Hills and Mystery Spots are caused by very high concentration of Type B dark matter at these special locations on earth as described in details in my companion web pages at:

Note: I started presenting this Web Page (1) on January 3, 2007 soon after my Travelogue website ( WWW.SHLTRIP.COM ) was established in December 2006. I have been revising and updating this web page from time to time as I gain more insight and relevant information from my ongoing research on this project. Most recent update of this web page was on March 11, 2017. As of May 15, 2017, this web page has been accessed at least 24,183 times by my friends and strangers all over the world.

I presented highlights of my 23 year research on this project in a meeting of IEEE (Institute of Electrical and Electronics Engineers) New York Section in Long Island University, Brooklyn Campus, on April 24, 2015 and in another IEEE meeting in Monmouth County Library in Manalapan, New Jersey, USA on September 29, 2016.The second meeting was co-sponsored by IEEE New Jersey Coast Life Member Group and IEEE New Jersey Coast EMC/VT/AP Chapter.

The PowerPoint file presented by Dr. Sing Lin on September 29, 2016 is in the following:

Many people have encountered or observed and reported a strange gravity mystery on strange slopes of paved roads at hundreds of special locations all over the world. People pour water on the paved surface of such strange slope and water flows uphill. People put plastic water bottle or basket ball on the paved surface of such strange slope and the plastic water bottle with water or the basket ball rolls uphill. Vehicles with transmission shifted to neutral gear and brake released simply roll uphill on such strange slopes of paved roads. Such strange gravity mystery has been known for at least 80 years.

More detailed information with eight pictures of a sample famous Gravity Hill known as Magnetic Hill near the City of Moncton in eastern Canada are given in my Web Page (4) at:

Historically, there are many kinds of names being used for such Gravity Hills at different parts of the world, such as gravity hill, antigravity hill, Confusion Hill, Magnetic Hill, Magic Hill, Mystery Hill, Magnetic Spot, Electric Brae, Spook Hill, Anti-Gravity Point, Strange Slope, etc.

In my companion web pages on this topic, I shall use “Gravity Hill” to refer to all such strange slopes of paved roads exhibiting such strange Gravity Hill Mystery at hundreds of known special locations all over the world. Several sample lists of the local names and the locations of these hundreds of Gravity Hills are collected in Section 4 in this web page.

The length of Gravity Hills usually is a few hundred feet, but it varies from one Gravity Hill to another Gravity Hill.

1.1.1 My Personal Experience on Gravity Hills

I visited the Magnetic Hill near Moncton in eastern Canada twice in 2005 and 2006. I have also visited three Gravity Hills in Pennsylvania and two Gravity Hills in New Jersey. With these visits, I got plenty of personal experience on such Gravity Hill Mystery.

At Oregon Vortex in Oregon, USA and several other similar known Mystery Spots, the well known Shrink-and-Grow Mystery is the significant change (by several inches) of relative heights of two persons when they switch their standing positions on a level platform inside the Mystery Spot area.

Please see the following six movie clips of demonstration of Shrink-and-Grow Mystery at four different Mystery Spot areas:

The demonstration of Shrink-and-Grow Mystery in Mystery Hill in North Carolina at:

There are more movie clips on Shrink-and-Grow mystery posted on YouTube website by several other visitors showing their excitement from their trips to watch such Shrink-and-Grow mystery.

In such demonstrations, usually the tour guide uses a carpenter's (bubble based) level to convince the group of tourists watching this Shrink-and-Grow demonstration that the demonstration platform is level because the liquid bubble in the horizontal tube in carpenter's level is in the middle position indicating a level ground. Some visitors have also brought in their own carpenter’s levels which also show that the demonstration platform is level.

Notice that in these two demonstrations at Cosmos Mystery Area in South Dakota and at Mystery Spot in California, the two persons are separated by only about two feet and yet their heights can change so much when they switch their standing positions.

1.2.1 Everybody See the Same Shrink-and-Grow Mystery No Matter Where They Stand To Watch

Such mystery demonstration is usually repeated many times every day for many tour groups to see. Sometimes, a large visitor group comes with large number of visitors surrounding the demonstration. Different visitors see the demonstration from different angles, different distances and different positions. But all visitors see the same mystery of substantial change in relative height no matter what angle, what distance or what position that the visitors are looking at the demonstration. Sometimes, the tour guide let two visitors stand on the two positions to do the demonstration. Such two visitors as demonstrators looking at each other also see the same surprising significant change in their relative height.

It is hard for me to believe that this is an illusion because seeing this Shrink-and-Grow mystery does not require the viewer or the photographer to be at certain special angle or special distance or special position or special trick to be able to see such significant change in relative height.

It is quite entertaining to all visitors even though nobody, not even the tour guide, know why the relative height change so much when the two persons switch their standing positions on the level ground.

1.2.2 Several Known Mystery Spots

Similar Shrink-and-Grow Mystery exists at several Mystery Spots such as:

Teton Mystery (Spot) at 9800 South US Highway 89, Jackson, in Wyoming,

Mystery Hill at 129 Mystery Hill Lane, Blowing Rock, North Carolina,

etc.

The typical size of such Mystery Spot area is about 100 feet in diameter but varies from one Mystery Spot area to another Mystery Spot area. The distance between the two standing positions on the demonstration platform may be about two feet to ten feet depending on the location in the Mystery Spot area.

Historically, there are several kinds of names being used for such Mystery Spot area at different locations, such as Oregon Vortex, Montana Vortex, Cosmos Mystery Area, Mystery Spot, Mystery Hill, Confusion Hill, Teton Mystery, etc.

In my companion web pages on this topic, I shall use Mystery Spot areas to refer to these special locations exhibiting such Shrink-and-Grow Mystery.

1.2.3. My Personal First Hand Experience of Shrink-and-Grow Mystery

I visited the Mystery Spot near Santa Cruz, California three times: first time in 1993, the second time in 2012 and the third time in 2016.

I visited Oregon Vortex Twice: first time in 2004 with pictures on my web page at:

With such visits, I got plenty of my personal experience on such Shrink-and-Grow Mystery plus other mysteries in these Mystery Spot areas.

1.3. The Illusion Theory

Many people simply dismiss such strange Gravity Hill Mystery on those Gravity Hills and Shrink-and-Grow Mystery in those known Mystery Spot areas as illusion. The Illusion Theory asserts that: (1) the gravity is normal, with no horizontal component, at all such special locations of Gravity Hills and Mystery Spot areas, (2) all the observed strange Gravity Hill Mystery in all those Gravity Hills and Shrink-and-Grow Mystery in those known Mystery Spots are due entirely to illusion in human perception.

It is noted that several mysteries in astronomy observations, such as galaxy rotation curve problem, the colliding Bullet Cluster of galaxies, and the accelerated expansion of universe, have attracted great attention of many scientists. Many scientists all over the world have been working very hard on the great mysteries of dark matter and dark energy for many years. But we, collectively, still know very little about dark matter and dark energy.

Yet many people, including many scientists, with only 30-minute tour of a Mystery Spot area or a Gravity Hill, and some never toured any of such Mystery Spot area or Gravity Hill, can reach their conclusion with "very strong confidence," to assert that all these mysteries on earth are just illusion and fake. If you read the results of my 23-year research on my Web Pages (1), (2) and (3), you will realize that these mysteries on earth are due to the great mysteries of dark matter at these special locations. They are as complex and challenging as those mysteries observed in astronomy. One wonders how can so many people, including many scientists, solve all these great mysteries of dark matter on earth and reach their conclusion of illusion so easily and so fast in 30 minutes!

Some people have also done some bubble based tests and measurements on some of those Gravity Hills and claimed that they have proved that it is an illusion. All these tests, using carpenter's level or land survey instruments, are based on liquid bubble to establish the critical reference plane for measurements. But we know that the liquid bubble can be affected by the horizontal component of abnormal local gravity and can give false indication of "level" negating the results of such bubble based measurements. In other words, those bubble based measurement results supporting the Illusion Theory are wrong because the local gravity at those special locations is abnormal with a significant horizontal component as described in the following sections.

1.4 Main Goals of this Web Page

The main goal of this web page is to present eleven sets of important evidences, found in my 23-year research, to show that (1) the Illusion Theory is wrong for Gravity Hill Mystery and Shrink-and-Grow Mystery, and (2) Gravity Hill Mystery and Shrink-and-Grow Mystery are real and are caused by existence of significant abnormal local gravity, especially significant horizontal component of gravity, at these special locations.

1.5 Scientific Explanation for Shrink-and-Grow Mystery

The scientific explanation, with several possible contributing factors, for the Shrink-and-Grow Mystery is given in Section 2 and Appendix A in my Web Page (6) at:

Figure 2 - The Illusion theory asserts that (1) the human perceived bottom of the Magnetic Hill is “higher” than the human perceived top of the Magnetic Hill due to illusion effect, and (2) all those vehicles are rolling downhill on the Magnetic Hill even though everybody see those vehicles as rolling uphill.

From my viewpoint based on my personal firsthand experience on the Magnetic Hill, this is a strong evidence that the bottom of the Magnetic Hill is indeed lower than the top of the Magnetic Hill because we cannot see the bottom from the waiting area on the top of the Magnetic Hill as shown on Picture 8.

If the bottom of the slope were “higher” than the top of the slope as asserted by the "Illusion Theory" in Figure 2, then we, standing on waiting area, should be able to see the "higher" bottom.

However, the fact that on the waiting area in Pictures 8, we cannot see the bottom of the Magnetic Hill is a strong evidence that (i) the bottom of the slope is indeed lower than the top of the slope, and (ii) this strange Gravity Hill Mystery of vehicles rolling uphill is real and is NOT due to illusion.

Furthermore, some other people took some pictures and movie clips from the bottom of the Magnetic Hill as shown in Appendix A in the following. These pictures and movie clips from the bottom indicate that they cannot see the large waiting area on the top as viewed from the bottom. Such pictures and movie clips from the bottom provide further confirmation that the bottom is indeed lower than the top of the Magnetic Hill.

2.1.2. My Motivation to Search for More Evidences Against Illusion Theory

Some people have been using the argument on how the roadside trees and shrubs are tilted on Gravity Hills to create the illusion. Here on this Gravity Hill in eastern Canada, I am not using how the roadside trees and shrubs are tilted to determine which end of the slope is higher. My criterion is very simple here. If the bottom of the slope were higher as asserted by the illusion theory, we should be able to see the higher "Bottom" from the large waiting area. But the fact is that we cannot see the bottom of the slope from the waiting area as shown on Picture 8. Such simple criterion convinces me that the human perceived bottom of this Gravity Hill is indeed lower than the top.

This is the first evidence that leads to my strong doubt on the validity of the popular and entrenched Illusion Theory. This personal experience at Magnetic Hill in eastern Canada gives me strong motivation in my 23-year research to search for other additional independent evidences against the Illusion Theory. That is how I found the other ten sets of evidences as described in the following sections.

2.2.. Second Set of Evidence against Illusion Theory - Gravity Hills on Coastal Roads:

2.2.1 Lack of Horizontal Reference as support for Illusion Theory

Believers of Illusion Theory say that people often cannot tell which end of the slope of a Gravity Hill is really higher because there is no reference horizontal plane or horizontal line to help people to make correct determination. Therefore, human perceptions of the top and of the bottom of the slope are often wrong because of the illusion effect created by the nearby trees, shrubs and environment.

But several known Gravity Hills are on coastal roads where the vast horizontal line of the nearby ocean is readily visible as the horizontal reference to all visitors of such coastal Gravity Hills. Existence of such coastal Gravity Hills, described in the following, refutes the argument of lack of horizontal reference as a support for Illusion Theory.

2.2.2. Wrong Measurement Results as further support for Illusion Theory

However, the Illusion Theory still asserts that human perceptions of the top and of the bottom of such coastal Gravity Hills are still "wrong" because their supporting bubble based measurements by carpenter’s level or by land survey instrument indicate that the human perceived bottom is “higher” than the human perceived top of such coastal Gravity Hill.

On the other hand, the four sets of evidences in Sections 2.3 to 2.6 indicate that significant abnormal local gravity has been detected at several special locations in the known Mystery Spots.

The key defect in these existing bubble based measurements by carpenter’s level or land survey instrument on Gravity Hills supporting Illusion Theory is that the surveyors never checked to see if the local gravity is normal or not. They just assumed (erroneously) that the local gravity is normal and went ahead to do the bubble based measurements blindly. In this way, the liquid level bubble and the plumb line used in such land survey measurements are affected by the significant horizontal component of abnormal local gravity on such Gravity Hills such that the measurement results are wrong as explained in more details in Appendix E with Figure E-1 and Figure E-2 in Web Page (4).

Again, these movie clips all show that the nearby ocean and its horizontal line are readily visible by everybody on this coastal Gravity Hill on the coastal road A719.

Therefore, the human perception of the top and the bottom of such coastal Gravity Hill should be correct because the reference horizontal line is readily visible in the nearby ocean. This means the Gravity Hill Mystery is real on such coastal Gravity Hill where vehicles roll uphill.

The first evidence from Magnetic Hill and the second evidence from this coastal Gravity Hill encourage me to continue my search for more independent evidences against Illusion Theory.

2.2.4. More Examples of Known Coastal Gravity Hills

The second example of coastal Gravity Hill is known as Magnetic Hill, located on the coastal road A27 between Ballabeg and the Round Table crossroads, at Ronague near Colby on Isle of Man in the Irish Sea in Great Britain. On such coastal Gravity Hill, visitors can see vehicles rolling uphill and also see the reference horizontal line on the nearby ocean as shown in the following YouTube videos:

In addition to these two examples of Gravity Hills on coastal roads, there are more reported Gravity Hills on coastal roads such as:

Known as Anti-Gravity Point on a coastal road at a place called Mirbat which is about 40 km east of coastal City of Salalah in southern part of Oman (on the southeast coast of the Arabian Peninsula), and

A Gravity Hill in Cascais, on a coastal road N247 on a hill near Malveira da Serra and Guincho Beach, West of Lisbon, Portugal.

2.2.5. Important Lesson learned from these Coastal Gravity Hills

These movie clips and pictures on coastal Gravity Hills show that the vast horizontal line of the nearby ocean is readily visible as the horizontal reference to all visitors to these coastal Gravity Hills. These coastal Gravity Hills refute the argument of the lack of horizontal reference as support for the Illusion Theory described in Section 2.2.1.

The remaining sets of evidences in sections 2.3 to 2.9 and Appendix E in Web Page (4) show that the bubble level based measurement results to support Illusion Theory are wrong because of the influence of the horizontal component of abnormal local gravity at these special locations of Gravity Hills and Mystery Spot areas. The existence of significant abnormal local gravity refutes the bubble based measurement results by carpenter’s level or by land survey instruments for support of Illusion Theory.

These coastal Gravity Hills teach us that when the bubble based measurements by carpenter’s level or land survey instrument show that the human perceived bottom is “higher” than human perceived top of a gravity hill, watch out! It is very likely that the bubble based measurement results are wrong and human perception is correct on such Gravity Hill because of the existence of significant abnormal local gravity at such special location.

In other words, when the bubble based measurement results are contrary to the human perceptions on which end of a Gravity Hill is higher, such contrary may become a detector of existence of significant abnormal local gravity causing the bubble based measurements to be wrong and to be in contrary to human perceptions.

2.3. The Third Set of Evidence against Illusion Theory - Detection of Abnormal Gravity with Horizontal Component at Mystery Spot in Michigan by Three Surveyors

According to the website of Mystery Spot in Michigan, in early 1950s’, three surveyors discovered the Mystery Spot at 150 Martin Lake Road, St. Ignace, Michigan, USA. They stumbled across an area of land where their surveying equipment did not seem to work properly. No matter how many times they tried to level their tripod, through the use of a plum-bob or bubble level, the plumb-bob would always be drawn far to the east, even as the bubble level was reading level as stated on the website of this Mystery Spot in Michigan at:

What this means is that the local gravity in that particular area is so abnormal that their bubble based leveling adjustment could not function properly. The abnormal local gravity has a significant horizontal component such that the gravity vector is not pointing vertically straight down, but is pointing at a significant slant angle. That is why the plumb-bob would always be drawn far to the east, while the bubble level on the top of the tripod is giving a "false" reading of level.

It is noted that in most areas where the earth gravity is normal and land surveyors can use their instrument to do land survey properly, when the level bubble on top of the tripod indicates achieving level, the plumb-bob will hang straight down vertically below the instrument as the normal behavior of the land survey instrument in the environment of normal earth gravity.

Therefore, this strange behavior of land survey instrument indicates that the local gravity at that particular location is very abnormal, and has a significant horizontal component.

More reports on Internet of difficulties in using land survey instruments at Mystery Spot in Santa Cruz, California and in Oregon Vortex in Oregon because of abnormal local gravity are collected in my website at:

Such detected significant abnormal local gravity at these three locations is the third evidence against Illusion Theory because Illusion Theory asserts that the gravity is normal, with no horizontal component, at all these special locations of Gravity Hills and Mystery Spot areas.

2.3.1. Detector #1 for Detection of Significant Abnormal Local Gravity

For the purpose of discussion in my companion web pages on this project, I shall call such strange behavior of land survey instrument as the Detector #1 for detection of significant abnormal local gravity with significant horizontal component.

2.4. Fourth Evidence against Illusion Theory - Asymmetric Pendulum

The fourth set of evidence against Illusion Theory is asymmetric behavior of pendulum observed and measured in Oregon Vortex in Oregon, USA. The idea is quite simple: If the local gravity were normal at Oregon Vortex as asserted by the Illusion Theory, then a pendulum should swing symmetrically as expected. But, if the local gravity in Oregon Vortex is abnormal with a significant horizontal component of gravity, then the simple regular pendulum will show asymmetric behavior because of the horizontal component of gravity.

The fact in Oregon Vortex and in other Mystery Spots is that the pendulum swings from its equilibrium position is much longer in one direction than it is in opposite direction.

Pendulum experiments have been done at Oregon Vortex in Oregon, USA. Researchers push the weight at the bottom of the pendulum away from its equilibrium position, and found that it is harder to push in one direction vs. opposite direction. Their measurements in Oregon Vortex indicate that the difference in required forces to push the weight in the two opposite directions is about 20%.

This measured result is a good evidence for the existence of significant abnormal local gravity with significant horizontal component in such special area. It is, therefore, a good evidence against the Illusion Theory which asserts that the gravity is normal with no horizontal component in all these special locations of Mystery Spot areas and Gravity Hills.

Five demonstrations of such asymmetrical behavior of pendulum can be seen near the end of a movie taken from the Mystery Hill in North Carolina at the following YouTube website:

Another strange behavior of a pendulum in a Mystery Spot can be seen on Page 5 in here.

2.4.1. Detector #2 for Detection of Significant Abnormal Local Gravity

The asymmetric behavior of a pendulum is the Detector #2 for detection of significant abnormal local gravity with significant horizontal component.

2.5. Fifth Set of Evidence against Illusion Theory – Measured Strength of Local Gravity Differing Significantly from Normal Value

Nick Nelson and Igor Shnaper had conducted a simple experiment and concluded that the value of gravity g was equal to 8.89 m/sec2 in Oregon Vortex. This is about 10% smaller than that of normal value of g = 9.88 m/sec2.

They obtained this value by performing a simple experiment in Oregon Vortex by hanging a brass plumb bob from a rafter. They measured the length of the string and timed the swings to calculate the value of the gravity g in the Oregon Vortex.

Their measured results indicate that the strength of gravity in Oregon Vortex is 10 % less than that of normal gravity outside of Oregon Vortex. This means the strength of the abnormal local gravity in that special area is at least 10% of the normal earth gravity on the earth surface.

Such measured significant abnormal local gravity is the fifth evidence against Illusion Theory because Illusion Theory asserts that the gravity is normal in all these special locations.

The 10% difference in gravity may looks small and unimpressive to many people. But for people who pay some attention to geophysics, especially the science of earth gravity, will realize that the 10% difference in earth gravity on earth surface is extraordinary and is a big deal. For example, the summaries of the known facts about earth gravity on earth surface in the following two references:

indicate that the variation in earth gravity across the earth surface should vary by no more than 0.7%.

Usually, the earth gravity on earth surface is quite stable, normal, and varies by less than 0.7% across earth surface. However, the extraordinary variation of 10% of gravity in the Mystery House in the very special location of Mystery Spot area indicates that the gravity in such special area is very abnormal.

2.5.1. Detector #3 for Detection of Significant Abnormal Local gravity

The measured strength of local gravity that differs significantly from the normal strength of normal earth gravity on earth surface is the Detector #3 for detection of significant abnormal local gravity.

2.6. Sixth Set of Evidence against Illusion Theory - Detection of Abnormal Gravity by Gravitational Time Dilation

Einstein’s Theory of General Relativity predicts that the closer the clock is to the source of strong gravity, the more slowly time passes. In other words, clocks which are far from massive bodies (or at higher gravitational potentials) run faster, and clocks close to massive bodies (or at lower gravitational potentials) run slower. This gravitational time dilation has been verified and demonstrated experimentally many times as described in the following Wikipedia website:

Nick Nelson has been doing research on gravity mysteries of Oregon Vortex for about 30 years. He worked in Oregon Vortex for two years in 1999 and 2000. He also visited several other Mystery Spots and has substantial experience and knowledge on various gravity mysteries in these Mystery Spots. Based on the concept of gravitational time dilation from Theory of General Relativity, Nick Nelson, with help from the management at the Oregon Vortex, performed an important experiment in 1999 and 2000 using four identical digital watches to measure the gravitational time dilation inside and outside of Oregon Vortex. The results, after 90 days of measurement, indicated that time in the Oregon Vortex run a quarter of a second a day slower inside than outside as described on Page 17 in here.

Doug Vogt, Nick Nelson and Dr. Nikolay Barashkov performed similar important measurements inside and outside the Vortex at Confusion Hill at Piercy in northern California, Magnetic Hill in Penngrove, California and Mystery Spot in Santa Cruz, California in 1996 to 2002 time frame. These measurements all found similar and significant gravitational time dilation in such Mystery Spot areas.

Similar gravitational time dilations have also been observed in several locations in Russia. Some Russian scientists have been investigating and doing research on such strange places in Russia with such gravitational time dilation.

In southwestern China in the mountainous area of Yunnan and Tibet, there is a very special valley known as Shangri La as described in the 1933 novel "Lost Horizon" written by British author James Hilton. That book was also turned into a movie, also called Lost Horizon, in 1937 by director Frank Capra. According to this novel, a special feature of Shangri La is that people living in Shangri La age much slower than people living outside of Shangri La. (However, the novel and the movie might have dramatized and exaggerated the effects of gravitational time dilation.) The ancient Tibetan scriptures indicate the existence of seven such special places according to the following Wikipedia website:

May be it is also worthwhile for some scientists to seek out such special location(s) including the well known Strange Slope near ShenYang in northeast China plus many other similar Strange Slopes and to do the clock speed measurements to see if significant gravitational time dilation indeed exists in such special locations in China.

Such information indicates that Mystery Spot areas may exist not only in USA as listed in Section 1.2.2, but also in other parts of the world such as Russia, China, etc.

2.6.1 Sixth Set of Evidence against Illusion Theory

Such measured results of significant gravitational time dilation in Oregon Vortex in Oregon, in Confusion Hill in northern California, in Magnetic Hill in Penngrove, California and in Mystery Spot in Santa Cruz, California are proof that the local gravity in these Mystery Spot areas is significantly abnormal based on Einstein’s Theory of General Relativity. This is an important evidence against Illusion Theory because Illusion Theory asserts that the gravity is normal in all those Gravity Hills and Mystery Spot areas and all the observed strange gravity phenomena are due entirely to illusion in human perception.

2.6.2. Detector #4 for Detection of Significant Abnormal Local Gravity

The measurement of significant gravitational time dilation is Detector #4 for detection of significant abnormal local gravity.

2.7. Seventh Set of Evidence Against Illusion Theory: Variation of Body Weight with Location

On January 11, 2016 I visited the Mystery Spot in Santa Cruz for the third time to do a simple experiment and to gain more insight on the Mystery Spot. I brought a simple body weight scale to measure my body weight on the two standing positions of demonstration platform of Shrink-and-Grow mystery near the entrance of this Mystery Spot. I brought an analog body weight scale with a big dial to show the measured body weight. The brand of this scale is Health-o-Meter, Model HAB401DQ-99 G263NT.

The measured body weight of me standing on these two standing positions are different and are 206 lb and 211 lb respectively. The distance between these two standing positions is only about 2 feet. This is a simple experiment to prove that the local gravity in this Mystery Spot in abnormal. In this experiment in the winter of January 11, 2016, I was wearing heavy winter coat, a pair of shoes and carrying my smartphone and camera. The measured body weight of me in this experiment included all these heavy stuff on me. More details of this experiment are on my web page at:

As we know that the normal gravity of the earth is quite uniform over very large area on earth surface and the measured body weight under normal earth gravity should be the same over very large area. But the simple body weight measurements in this Mystery Spot indicate that the gravity in this Mystery Spot does not behave like the normal earth gravity.

Therefore, the results of this simple experiment of body weight measurements in this Mystery Spot in Santa Cruz is the Seventh Set of evidence against the Illusion Theory because Illusion Theory asserts that the gravity in these Mystery Spot areas are all normal and all the observed mysteries are due to illusion in human perception.

2.7.1. Detector #5 for Significant Abnormal Local Gravity

The Detector #5 is to measure the body weight at several different locations. If the local gravity is normal, the measured body weight should be identical at all these locations. But if these measured body weight data are not identical at all these locations, such variations are an indication of existence of significant abnormal local gravity.

2.8. 8th Set of Evidence Against Illusion Theory - Failures of Some Digital Electronic Devices in Mystery Spot Areas

Many visitors (including I) have reported their strange experience of failures or malfunction of some (but not all) of their digital electronic devices when they are in a Mystery Spot area. These digital electronic devices work perfectly when they are outside of the area of the Mystery Spot, but do not work properly when they are inside the Mystery Spot area.

For example, in my second visit of the Mystery Spot in Santa Cruz, California in 2012, my younger son, living in Mountain View, California, responded to my request, brought his digital body weight scale from his apartment to Mystery Spot intended for our simple experiment to measure my body weight on the two standing positions of Shrink-and-Grow Mystery demonstration platform. However, that digital body weight scale did not work in the Mystery Spot. It is very strange in that the digital body wight scale works properly in my son's apartment in Mountain View both before and after our trip to Mystery Spot. We still do not know why that digital body weight scale did not work in the Mystery Spot.

On the other hand, in my third visit of Mystery Spot in Santa Cruz on On January 11, 2016, we brought an analog body weight scale for my body weight measurements, the analog body weight scale worked well with no problem.

I had another experience of very strange behavior of my portable GPS navigator when it was near the area ofa Mystery Spot, known as Cosmos Mystery Area, in South Dakota. It is described in more details in Section 8on my web page at:

Several other people have also reported similar failures or malfunction of their digital electronic devices when they are in a Mystery Spot area. Some more examples can be seen here, here, here and Page 8 in here. By digging into visitors' reports on Internet, one may see more examples of such strange failures of digital electronic devices in a Mystery Spot area.

may be one of the possible reasons for such strange failures or malfunction of some digital electronic devices in Mystery Spot areas. Some of such digital electronic devices are using highly miniaturized Integrated Circuit (IC). The shrinking of space by the fountain of high density dark matter in a Mystery Spot area may squeeze too much on these highly miniaturized IC leading into their failures or malfunction.

If the mysteries in these Mystery Spot Areas were all due to illusion as asserted by the Illusion Theory, such illusion would not be able to cause such strange failures or malfunction of such digital electronic devices. Therefore, such strange failures or malfunction of these digital electronic devices are strong evidences against the Illusion Theory for these mysteries in these Mystery Spot areas.

2.9. 9th Set of Evidence Against Illusion Theory - Visitors Standing Tilted and Cannot See Their Own Feet

In a typical Mystery Spot, the gravity is abnormal not only in the sense that the body weight varies from one location to another, but the vector direction of the gravity also varies from one location to another and is NOT always vertical. This is most profound near the Mystery House where we can feel a very strong horizontal gravity pulling on our bodies. In order to maintain our balance, the visitors near or inside the Mystery House have to hold tight to the wood guard rails on the wall of the Mystery House to counter that strong horizontal gravity pull from an unknown source. If not holding on to the wood guard rail on the side wall of the Mystery House, the free standing visitors realize that their bodies are leaning at a very large angle (e.g., 17 degrees) from the vertical direction. The visitors can verify such large leaning angle when they look straight down and find that they cannot see their own shoes or feet.

Some examples of such horizontal pull and visitors standing with large leaning angle can be seen in the following YouTube movie from Mystery Hill in North Carolina:

Furthermore, if we take just a few steps away from the Mystery House, the horizontal pull on our body diminishes substantially.

The strength of such horizontal gravity varies with location in the Mystery Spot area and is usually strongest near or inside the Mystery House. Therefore, the leaning angle of free standing visitors in Mystery Spot also varies with location and is largest when standing near or inside the Mystery House.

Such location varying horizontal directed gravity is the Eighth Evidence against the Illusion Theory because Illusion Theory asserts that the gravity in such Mystery Spot is normal, implying having no horizontal component.

In fact, such significant horizontal component of the significant abnormal local gravity is an important contributor to the various mysteries observed in those Mystery Spot areas and in hundreds of Gravity Hills all over the world.

2.10. 10th Set of Evidence Against Illusion Theory - Many Visitors Get Seasick

When standing near or inside the Mystery House which is near the center of a Mystery Spot area, many visitors feel seasick, or motion sickness or nausea or dizzy.

Furthermore, hundreds of years ago, local Native Americans knew the Mystery Spot area in southern Oregon as "Forbidden Ground" because their horses refused to go into such strange area. In those early days, there was no tilted Mystery House in such Mystery Spot area. Therefore, such strange effects of Mystery Spot on human being and horses are not due to the illusion effect of the tilted Mystery House because the tilted Mystery House did not exist in such Mystery Spot area during those early days hundreds of years ago.

that such effects of Mystery Spot area on human being and horses are due to the strong time varying abnormal local gravity in Mystery Spot area. The effects of such strongly time varying gravity on human being and other animals are similar to those on a boat bobbing up and down on rough sea, or on a vehicle in unsteady jerky motions or on an airplane in turbulent air.

indicates that all molecules in human body are shrunk by several percent when visitors are near or inside the Mystery House. Such shrinking of all molecules in human body may be another contributor to the feeling of seasick,or motion sickness, or dizzy or ringing in the ear.

Therefore, such strange effect of Mystery Spot on human being and other animals is one more evidence against the Illusion Theory because Illusion Theory asserts that the gravity in the Mystery Spot is normal (with no strong time variation) and all observed and experienced mysteries in Mystery Spot are due entirely to illusion in human perception. If the gravity were normal in the Mystery Spot area as asserted by the Illusion Theory, the normal and static gravity would not be able to cause many visitors to feel seasick or motion sickness or nausea or dizzy and to cause horses to refuse to go near the Mystery Spot area.

2.11. 11th Set of Evidence from Shrink-and-Grow Mystery

In the demonstration of Shrink-and-Grow Mystery from Oregon Vortex in the following movie clip:

when the lady is on left side of the demonstration platform, the long rod resting on the heads of the lady and of the man is almost horizontal indicating that the two people are almost equal in their heights, but when the man is on the left side, the long rod resting on the heads of the lady and of the man is tilted at a substantial angle indicating that the man is much taller than the lady. This is a simple proof that the Shrink-and-Grow Mystery is real and is not just an illusion in human perception.

In the demonstration of Shrink-and-Grow Mystery in Mystery Hill in North Carolina at:

again, when the man is on left side (north side), the man looks much taller than the lady, but when lady is on the left side (north side), the man and the lady are almost equal in height. Furthermore, the author took screen shots from the movie to get the pictures of the Shrink-and-Grow Mystery. The author then cut out the pictures of the man and the lady at those two standing positions, and put the cut-out pictures of the man and the lady side by side for height comparisons. Such side-by-side comparisons of cut out pictures indeed show that the man is much taller on north side and becomes much shorter on south side. Similarly, the lady is much taller on north side and becomes much shorter on south side. Again, such comparisons are proof that the shrink-and-Grow Mystery is real and is not an illusion in human perception.

Therefore, these two sets of Shrink-and-Grow demonstrations together are 11th set of evidence against Illusion theory for these mysteries on earth.

3. More on Illusion Theory

The Illusion Theory for the strange gravity phenomena on Gravity Hills and Mystery Spot areas has been known for many years. Many people believe in the Illusion Theory. There may be several reasons contributing to such popularity of Illusion Theory for so many years, including:

(1) Many people are unaware of these eleven sets of evidences against Illusion Theory as described in this Web Page (1),

(2) Many people are unaware of the serious defect in the erroneous results from bubble based measurements that support the Illusion Theory as described in Appendix E in Web Page (4)

(3) Not all gravity hills are equal. Many people visited only feeble Gravity Hills and got ambiguous feeling of the weak strange phenomenon as described in more details in Section 7 on my Web Page (4). These people then easily get the feeling that such feeble and ambiguous strange feeling may be just an illusion.

(4) The complicated science, especially involving the great mysteries of dark matters, associated with the Gravity Hill Mystery and with Shrink-and-Grow Mystery as described in my companion Web Pages (2) and (6), is too difficult and complicated for many tourists to deal with. It is much easier to say it is just an illusion and to sweep all the complicated and hard stuff of science under the rug.

(5) For business purpose of roadside tourists' attraction, a tilted Mystery House is added near the center of a Mystery Spot area to enhance the “mysteries” and the fun in these Mystery Spots. Such additions are quite successful from commercial viewpoint to attract more visitors and more income for the business of Mystery Spots. Such addition of tilted Mystery House also makes an important contribution by attracting the attention of many science oriented researchers, including me, to do scientific research on these gravity mysteries.

But such addition of a tilted Mystery House has an unfortunate effect on scientific research on such gravity mysteries. Such addition of tilted Mystery House is quite obvious to create illusions to many visitors. In this way, many people naturally believe that all mysteries in such Mystery Spots are just illusions.

This unfortunate effect of “Throw out the baby with the bathwater” caused many people, including many scientists, to believe that the Gravity Hill Mystery and the Shrink-and-Grow Mystery are just parts of that whole package of illusion tricks of the tilted Mystery House.

From scientific viewpoint, the Gravity Hill Mystery and the Shrink-and-Grow Mystery are real and can stand on their own feet without the need for the tilted Mystery House to confuse the issue. In fact, there is no tilted Mystery House on all those hundreds of Gravity Hills all over the world. Furthermore, if you view the video recordings of the Shrink-and-Grow demonstrations in Section 1.2, you will see that the demonstration platforms are in outdoor open environment and far away from the tilted Mystery House. In other words, the Shrink-and-Grow Mystery and the Gravity Hill Mystery do not depend on the tilted Mystery House to create illusions.

(6) Real and Fake Mystery Houses: Some roadside tourist attractions of Mystery Spots are real with existence of significant abnormal local gravity causing those gravity mysteries. But some of the roadside tourist attractions of Tilted Mystery Houses are fake and are depending purely on the illusion effects of the tilted Mystery House to create some entertaining mysteries. With many years of experience as a tour guide in Mystery Spots and extensive research on such mysteries, Nick Nelson is able to tell if a Mystery Spot is real or fake as shown on this list.

An important signature of a real Mystery Spot is the existence of significant abnormal local gravity, especially significant horizontal component of local gravity causing many of observed gravity mysteries. Therefore, a scientific way to test if a Mystery Spot area is real or fake is to test for this important signature of significant abnormal local gravity.

(7) Some people subconsciously assume that normal earth gravity is the only force pulling on the vehicles rolling up the Gravity Hill (i.e., assuming that the local gravity is normal). With such assumption, they believe that whichever direction the vehicle is going on the Gravity Hill, that is the downhill direction because the normal earth gravity always pulls the vehicle to go downhill. If the slope of the road and its surrounding trees, shrubs etc. make people feel that it is an uphill slope, then it must be an illusion because normal earth gravity always pulls the vehicle to go downhill.

But the six sets of evidences in Sections 2.3 to 2.8 show that the local gravity is significantly abnormal with a significant horizontal component at these special locations of Gravity Hills and Mystery Spots. Therefore, the assumption of normal earth gravity on Gravity Hills by many people is not valid. In addition to the normal earth gravity, there is an additional gravity force coming from another source pulling on the vehicle. Let me use a visible extra force to make the point more visible and clear in the following:

In many mining operations, a powerful motored winch at the top of a steep slope and a strong steel cable are used to pull the mining cart to move uphill. In such case, the normal earth gravity is not the only force pulling on the mining cart, there is the powerful force on the steel cable coming from the powerful motor winch on the top of the hill to pull the mining cart to move uphill. In such case with two forces pulling on the mining cart, the direction that the mining cart is moving is NOT always downhill because normal earth gravity is NOT the only force pulling on the mining cart.

The situation on the Gravity Hill is similar to that of the mining cart on the uphill slope except that the visible steel cable is replaced by the invisible extra gravity force from the high density dark matter and the powerful motor winch on the top of the mining uphill slope is replaced by an invisible fountain of high density dark matter (Please see my companion Web Page (2) on this invisible fountain of high density dark matter). In such situation similar to the mining uphill slope, the direction where the vehicle is moving on the Gravity Hill is NOT always downhill because normal earth gravity is NOT the only force pulling on the vehicle on a Gravity Hill. The extra force from the invisible fountain of dark matter is pulling the vehicle to move uphill. It is a real uphill slope and NOT an illusion. The vehicle needs extra force to pull it to roll up the real uphill slope just like the mining cart.

The six sets of evidences in Sections 2.3 to 2.8 indicate that such extra abnormal gravity force exists at these special locations of Gravity Hills and Mystery Spots.

3.1 Required Strength of Abnormal Local Gravity at Gravity Hills

The inclination angle of the slope on most Gravity Hills on typical paved road is usually quite small and gentle in the order of 2 to 5 degrees. The slopes on some feeble Gravity Hills are even smaller in the order of one degree or less. For such small inclination angles, the required component of abnormal local gravity force along the slope of the Gravity Hill to pull the vehicle (in neutral gear and brake released) to roll uphill is only a few percent of the strength of normal downward earth gravity on earth surface.

As an example, the measurement at Oregon Vortex as described in Section 2.5 indicates that the strength of abnormal local gravity in the Oregon Vortex is as strong as 10% or more of normal earth gravity on earth surface. Such measured result indicates that the strange source of abnormal local gravity is capable of producing the abnormal local gravity as strong as 10% or more of the normal earth gravity on earth surface.

The bodies of free standing visitors near or inside the Mystery House in Oregon Vortex are leaning at an angle of about 17 degrees. This is an indication of very strong horizontal component of abnormal local gravity. Such a strong horizontal component of abnormal local gravity is certainly able to pull a vehicle (in neutral gear and brake released) to roll uphill on a paved road with gentle slope of 3 to 5 degrees.

3.2 Significant Abnormal Local Gravity

Therefore, the term “significant abnormal local gravity” in my companion web pages means that the strength of the abnormal local gravity is in the order of a few percent or more of the strength of normal earth gravity on earth surface.

As explained in my companion Web Page (2), the source of such significant abnormal local gravity is an invisible fountain of Type B high density dark matter with a mass density at least 1,000 times greater than that of average ordinary matter on earth surface. When such invisible fountain of high density dark matter is on the top of a Gravity Hill, its abnormal gravity along the slope of the Gravity Hill can be as strong as 10% or more of normal earth gravity as indicated by the measurement in Oregon Vortex. Therefore, the strength of the abnormal local gravity is certainly strong enough to pull a vehicle (in neutral gear and brake released) to roll uphill on the gentle slopes of those Gravity Hills.

4. Many Other Locations with Similar Gravity Hill Mystery

In addition to the Magnetic Hill near Moncton in eastern Canada described in my Web Page (4) listed above and several coastal Gravity Hills described in Section 2.2, there are hundreds of other similar Gravity Hills all over the world. Several sample long list of known Gravity Hills are available at the following websites:

As reported on Internet, many people have done simple bubble based tests on several known Gravity Hills by using either a carpenter’s level or a land survey instrument. Such measurements found that the measurement results are in contrary to the human perceptions on which end of the Gravity Hill is higher.

Based on the lesson learned from the eleven sets of evidences in Sections 2.1 to 2.11, plus the explanation in Appendix E in Web Page (4), the bubble based measurements at these special locations are wrong because of influence of significant horizontal component of abnormal local gravity on the bubble in such measurement instruments. This means the contrary between bubble based measurement results and the human perceptions has become a detector of existence of significant horizontal component of abnormal local gravity at those locations of Gravity Hills.

However, it is still desirable to use one or more of Detectors #1 to #5 for more tests at those special locations to confirm the existence of significant horizontal component of abnormal local gravity at those special locations.

6. Generalization

Although the eleven sets of evidences came from experiments, tests and observations at a limited number of Gravity Hills and Mystery Spots, the simple bubble based tests have been done by many people on many other known Gravity Hills all over the world. These additional tests have consistently shown the contrary between the bubble based test results and the human perceptions on which end of the Gravity Hill is higher. Such consistency is a good indication that significant horizontal component of abnormal local gravity exist at many special locations of Gravity Hills all over the world such that the bubble level is giving false reading consistently on all these special locations .

However, it is still desirable to use one or more of Detectors #1 to #5 for more tests at those special locations to confirm the existence of significant horizontal component of abnormal local gravity at those special locations.

7. Great Mysteries of Dark Matter in Astronomy and on Earth

7.1 Dark Matter in Astronomy

Dark matter is one of the greatest mysteries in modern science. Thousands of scientists all over the world have been doing intensive research on dark matter for many years, but we collectively still do not know what dark matter is as of 2017. Our science so far knows only about 15% of our physical universe made of our familiar and observable ordinary matter, but still knows very little about the other 85% of our physical universe made of invisible dark matter which so far can be detected only through its gravitational effects.

However, the new discovery of space shrinking characteristics of dark matter as described in my Web Page (6):

provide use one more method to detect the effects of dark matter on ordinary matter in the future.

Dark matter does not emit light, does not reflect light, and does not absorb light such that we cannot see dark matter directly. Furthermore, dark matter rarely interacts with ordinary matter directly.

The existence of large amount of dark matter in the universe is inferred from several serious problems and mysteries in several different kinds of astronomy observations in last 80 years. These observations include:

(a) the observed galaxy rotation curve problem,

(b) high speed problem of galaxies in large clusters of thousands of galaxies,

(c) the way light ray bends, by gravitational lensing, as it travels to us across vast space from far distant galaxies and their clusters, indicating that there is much more material in the space there than we can see,

(d) Bullet Cluster of collision of two galaxy clusters,

(e) the power spectrum of Cosmic Microwave Background Radiation,

(f) required time for the formation of Large-Scale Structure (Cosmic Web) of galaxies and clusters, etc.

These observed problems and mysteries in astronomy seriously violate the known laws of physics unless large amount of invisible and mysterious dark matter is assumed to exist in the universe. These several different and independent observations consistently indicate that dark matter must exist and dark matter is five times more abundant than our familiar observable ordinary matter.

7.2. Dark Matter on Earth

Dark matter exists not only on galaxies many light years away, but also on our earth. At least twelve deep underground laboratories have been set up at several different locations on the earth and have been running for many years to try to detect dark matter on earth. But more than 15 years of experimental data from these deep underground laboratories have been very controversial. Two deep underground laboratories claim that they have detected dark matter, but 10 or more other deep underground laboratories keep on coming up empty handed. It is a serious dilemma in science community because such dark matter detections in two deep underground laboratories are NOT repeatable in other deep underground laboratories.

On the other hand, for more than 100 years, many people have observed and reported mysteries on earth at hundreds of locations all over the world. Examples of such observed mysteries include Gravity Hill mystery at hundreds of locations and Shrink-and-Grow mystery in several known Mystery Spots. These observed mysteries and problems on earth also seriously violate the known laws of physics. However, many people simply dismiss such observed mysteries on earth as illusion in human perception. (But nobody dismiss those observed mysteries and problems in astronomy as illusion in human perception.)

For most people who are believers of Illusion Theory, the simple word “illusion” is an easy way to avoid facing up to the serious issue of violation of known laws of physics. "Illusion" takes care of all the problems implying that there is no challenging science in such strange gravity phenomena and mysteries. Therefore, these Gravity Hill Mystery and Shrink-and-Grow Mystery have not attracted much attention of scientists for many years.

Being an engineer with a strong scientific curiosity, I have been investigating and doing research on these mysteries on earth for more than 23 years. I am an outsider in the community of scientists doing research on dark matter. Being an outsider, I am brining in out-of-box thinking that may be helpful to unlock the secret of dark matter.

Some friends suggested that may be the Gravity Hill Mystery and Shrink-and-Grow Mystery are caused by large amount of heavy metal ore under the ground at those special locations. I did some estimations and calculations following such suggestions and found that the mass densities of our familiar ordinary matters on or near earth surface are simply too low by at least three order of magnitude (i.e., a factor of 1,000) and are NOT able to produce such mysteries. In other words, producing such mysteries requires a very strange and unfamiliar material with a mass density at least 1,000 times greater than that of average ordinary matter on earth surface as explained in more details in my companion Web Page (2) at:

According to this Web Page (2), the source of significant abnormal local gravity at all these special locations of Mystery Spots and Gravity Hills is an invisible fountain of extreme high density Type B dark matter.

Without introducing the concept of dark matter, it is practically impossible to understand and to explain these two strange gravity mysteries. With 23 years of research, I develop the dark matter based theory that can provide scientific explanation for the well known Gravity Hill Mystery and Shrink-and-Grow Mystery.

The stonewall of Illusion Theory has been masking the very exciting and challenging science of mysterious dark matter embedded in Gravity Hill Mystery on hundreds of Gravity Hills and Shrink-and-Grow Mystery in several known Mystery Spots on earth surface. Breaking down the stonewall of Illusion Theory is a necessary and critical step to open up the treasure door of very exciting frontier of science of dark matters that are trapped and oscillating in the earth gravity well.

8. Concluding Remark

8.1 First Goal of My Research Project

The first goal of my research project, therefore, is to present eleven sets of evidences found in my 23 year research to show that the Illusion Theory is wrong. The first evidence came from my personal experience on the famous Magnetic Hill in eastern Canada. The second evidence came from my study of several known Gravity Hills on coastal roads. The seventh evidence comes from my simple body weight measurements in the Mystery Spot in Santa Cruz. The eighth evidence comes from my personal experience in two Mystery Spots. The remaining four sets of evidences came from the experiments and tests conducted by Nick Nelson, I. Shnaper, Dr. Nikolay Barashkov, Doug Vogt and three land surveyors in several Mystery Spots.

As soon as the stonewall of the Illusion Theory is broken down, an immediate challenging question that pops up is “What is the source of the significant abnormal local gravity at those special locations of Gravity Hills and Mystery Spots?” This important question is the driving force for my 23 year research leading into my companion Web Page (2) entitled “Dark Matter based Theory for Mystery Spots and Gravity Hills” at:

Opening this treasure door will enable many scientists to enter to experience the thrill of close encounters with Type B very high density dark matters on earth.

8.2 Second Goal of My Research Project

An immediate application of this dark matter based theory is to resolve the serious dilemma in and to validate the reported direct detection of dark matters in two of several deep underground experiments at various locations in the world as described in more details on my Web Page (3) at:

This theory shows that the distribution of Type B high density dark matter in the earth is NOT uniform, but is highly concentrated in thousands of narrow streams of high density dark matter that is trapped and oscillating inside earth gravity well. This theory is, therefore, able to provide a scientific explanation to resolve the serious dilemma on why two of the deep underground laboratories have detected Type B high density dark matter but many other deep underground laboratories have not detected dark matter. One should not expect all these deep underground laboratories to have the same probability for detecting Type B high density dark matter. It all depends on whether the dark matter detector in the laboratory intercepts one of thousands of narrow streams of very high density dark matter or not.

I need to convince the science community that Type B high density dark matter has been detected successfully already at the correct locations!

After the successful detection of dark matter, let us go one step further to find out more about the mysterious dark matter, and hence the other 85% of our physical universe as described in my third goal.

8.3 Third Goal of My Research Project

The third goal of my research project is to convince many scientists that these special locations of Gravity Hills and Mystery Spots on earth offer the golden opportunity for many scientists to conduct close-up hand-on advanced experiments to investigate the characteristics of dark matter, especially of extreme high density dark matter, at these special locations on earth.

********************************************Appendix A: Evidence as View from the Bottom of Gravity Hill (Magnetic Hill)

A picture taken by other people from the bottom of the slope of Magnetic Hill looking toward the top of the slope can be seen at the following website:

This picture shows that this camera at the bottom of the slope cannot see the large waiting area for the waiting line of vehicles at the top of the slope beyond the instructor and the orange color post.

If the bottom of the slope were higher than the top of the slope, as asserted by the Illusion Theory, this camera at the "higher" bottom would be able to see the large area of waiting line of vehicles beyond the position of the instructors and the orange post.

The fact that this camera at the bottom cannot see the large waiting area on the top of slope is evidence that the bottom of the slope is indeed lower than the top of the slope.

Similarly, many other people have also taken movie clips when their cars in neutral gear were rolling up this Magnetic Hill near Moncton as shown on the following sample YouTube websites:

In these three movie clips, notice that when their cameras in their cars are pointing to the top of the slope (where the instructors and the area for the waiting line of vehicles are located), the videos show that these cameras cannot see the large waiting area on the top of the slope.

The fact that these cameras at the bottom of the Gravity Hill cannot see the large area of waiting line of vehicles on the top of the slope is consistent evidence that the perceived bottom of the slope is indeed lower than the top of the slope.

Therefore, both the views in Pictures 7 and 8 from the area of the waiting line of vehicles on the top of the slope and the views from the bottom of the slope consistently indicate that the perceived bottom of the slope is indeed lower than the perceived top of the slope.
